CVE-2019-6976 (opens in a new tab)How to fix?
Upgrade Ubuntu:18.04 vips to version 8.4.5-1ubuntu0.1~esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream vips package and not the vips package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
libvips before 8.7.4 generates output images from uninitialized memory locations when processing corrupted input image data because iofuncs/memory.c does not zero out allocated memory. This can result in leaking raw process memory contents through the output image.
